The old menstrual cycle argument was based on the notion that women are too emotional for high office but that men do not lose their cool. (It helps if you don't know any men.) Now comes the migraine argument, used by former Minnesota Gov. Tim Pawlenty, also a GOP White House hopeful. He told reporters, "There's no real time off in that job."
Apparently, Western civilization would crumble if a female president spent an afternoon on a couch with a cold washcloth on her forehead, because then she wouldn't be able to play golf, pose for a photo opportunity or campaign for re-election like your usual president.
Oh, and, Gov. Pawlenty, if you're worried about a candidate's not being able to govern 24/7, don't play hockey.
